Loop and Arrays

Can I have 2 initializers, 2 conditions, 2 iterators?

for (initializer; condition; iterator){
    body
}

I am asking this because I want to compare 2 arrays

int[] v1 = new int[10];
int[] v2 = new int[10];

for(int i=0; int j=v2.Length; i<v1.Length; j>0; i++; j--)
{
     if(v1[i]==v2[j])
     {
        //do something
     }
}

Not exactly, you can declare and initialize multiple loop variables, but they need to have the same type. Further, you cant have multiple conditions, but you can combine them via logical operators:

for (int i = 0, j = 1; i < v1.Length && j > 0; i++, j++  )
{
    if (v1[i] == v2[j])
    {
        //do something
    }
}

what also works is to initialize earlier declared variables of different types:

int i; double j;
for ( i = 0, j = 1.5; ... )
